Abstract
Embodiments disclosed herein provide systems and methods for packet filtering in a wireless communication network. In a particular embodiment, a wireless network receives from a requesting device a request for a plurality of data packets to be transferred by a source for delivery to the requesting device. The network then generates session information associating the source of the data packets with the requesting device. Additionally, the network receives a first subset of the data packets from the source for delivery to a destination identified by the data packets. After receiving the packets, the network identifies a destination device based on the destination identified by the packets. The network processes the session information to determine whether the destination device is associated with the source of the packets. If the destination device is associated with the source, the network transfers the packets for delivery to the destination device.
